Helicopter propulsion systems are reviewed, and it is noted that helicopter development is paced to a major extent by the power plant. Power available, reliability, fuel consumption, power-to-weight ratio, and life-cycle costs are key parameters. The application of emerging technologies such as microelectronics, ceramics and other new materials and approaches, and the continuing refinement of the aerodynamics and dynamics of gas turbine power plants are discussed and noted to result in a...

Nuova Elettronica è una rivista italiana che si occupa di hobbistica elettronica. Creata da Giuseppe Montuschi nel 1969 a Bologna dalle ceneri della rivista Sistema Pratico . La periodicità di uscita a volte non viene rispettata prediligendo la qualità dei progetti proposti. Nonostante la rivista arrivi nelle edicole tramite il più grande distributore privato nazionale, la maggior parte dei lettori preferisce abbonarsi. Sono popolari le periodiche offerte di arretrati venduti a peso (14 kg...

TERC, of Cambridge, Massachusetts, developed a two-year (four-semester) instructional program designed to prepare technicians for the emerging electromechanical occupations in industry. The project was was completed in August 1973, and was supported by grant funds provided by the U. S. Department of Health, Education, and Welfare. This collection includes all 16 student manuals, which are all now in the public domain and free for reuse and redistribution. Each book's materials are presented in...

The handbook glossary provides terminology definitions for the important components and mechanisms which comprise a breech mechanism. Webster's Third New International Dictionary provides the following definitions- 1. Breech. The part of a cannon or other firearm at the rear of the bore. 2. Breech block. The block in breech-loading firearms that closes the rear of the bore against the force of the charge. 3. Breech mechanism. The mechanism for opening and closing the breech of a breech- loading...

The life prediction and reliability assessment of the M60 tank torsion bars were obtained from applying a methodology involving several disciplines. The disciplines included: structural mechanics, fracture mechanics, statistical reliability, mechanical testing, nondestructive examination (NDE), quality assurance (QA), and metallurgical and fractographic evaluations. The methodology was applied in order to obtain a procedure for increasing torsion bar life and enhance the reliability of the M60...

Design charts and tables have been developed for the elastic torsional stress analyses of free prismatic shafts, splines and spring bars with virtually all commonly encountered cross sections. Circular shafts with rectangular and circular keyways, external splines, and milled flats along with rectangular and X-shaped torsion bars are presented. A computer program was developed at the U.S. Army ARRADCOM, Dover, N.J. site which provides a finite difference solution to the governing (POISSON's)...

In this mathematical study on helical spring design, three basic types of load requirements are distinguished and treated individually: (1) the load at assembled height; (2) the load at minimum compressed height; and (3) the energy content of the spring. Conventional load and stress deflection formulas are modified by the replacement of dependent variables with independent values. The ratio of the final spring deflection over the working stroke is formulated to show the variation of the final...
